The moment of inertia precontrol assumes that there is an approximately linear relationship between the moment of inertia and the load torque.

The inverter must measure the pole position for motors not equipped with an encoder, or for encoders, which do not supply the information regarding the pole position. If you are using a Siemens motor, then the inverter automatically selects the appropriate technique to determine the pole position, and when required starts the pole position identification.

By deactivating the speed controller and directly entering the torque setpoint, the closed-loop speed control becomes closed-loop torque control. The inverter then no longer controls the motor speed, but the torque that the motor generates.

Advanced commissioning 6.6 Protection functions Protection functions The frequency inverter offers protective functions against overtemperature and overcurrent for both the frequency inverter as well as the motor. Further, the frequency inverter protects itself against an excessively high DC link voltage when the motor is regenerating. 6.6.1 Inverter temperature monitoring The inverter temperature is essentially defined by the following effects:...
Page 177 Advanced commissioning 6.6 Protection functions Overload response for p0290 = 0 The inverter responds depending on the control mode that has been set: ● In vector control, the inverter reduces the output current. ● In U/f control, the inverter reduces the speed. Once the overload condition has been removed, the inverter re-enables the output current or speed.
Page 178 Advanced commissioning 6.6 Protection functions Overload response for p0290 = 3 If you operate the inverter with increased pulse frequency, then the inverter reduces its pulse frequency starting at the pulse frequency setpoint p1800. In spite of the temporarily reduced pulse frequency, the maximum output current remains unchanged at the value that is assigned to the pulse frequency setpoint.

Procedure To replace the Control Unit without backed-up settings, proceed as follows: 1.
Page 271: Replacing A Control Unit With Active Know-How Protection
If the inverter settings can neither be copied nor forwarded, a recommissioning is required after inverter replacement. To avoid the recommissioning, you must use a Siemens memory card, and the machine manufacturer must have an identical prototype machine that it uses as sample.
Page 272 – Send the encrypted project to the end customer, e.g. via e-mail. 3. The end customer copies the project to the Siemens memory card that belongs to the machine, inserts it in the inverter and switches on the power supply for the inverter.
